Flying freehold explained

A flying freehold sounds exotic but simply means part of your freehold property sits above (or below) someone else's. It is more common than you'd think, in converted houses, properties over shared passageways, and old terraces, and it can affect mortgages, surveys and resale. Here's what buyers need to know.

In short

A flying freehold is where part of a freehold property overhangs or sits beneath another property or land that you don't own, for example a room built over a shared passageway, or a balcony extending over a neighbour's garage. The main issues are practical and legal: there may be no clear rights of support, access for repairs, or obligations on the neighbour to maintain the part beneath or beside your home. This can make some lenders cautious, so a small flying freehold is usually manageable (often with indemnity insurance), while a large one can limit your choice of mortgage. A solicitor should check the rights and covenants, and a surveyor should assess the structure before you buy.

What a flying freehold really means

Normally a freehold includes the ground beneath your home and the airspace above it. A flying freehold breaks that neat picture: part of your property exists over or under land or a building that belongs to someone else. Classic examples are a bedroom built above a shared alleyway, a room overhanging a neighbour's garage, or a basement extending under the property next door.

The opposite situation, where part of your land lies beneath someone else's property, is sometimes called a 'creeping freehold'. Both raise the same core questions: who has the right to support, access and repair the shared structure?

Common examples of flying freeholds

  • A room built over a shared passageway or driveway between two houses.
  • A balcony or bay window extending over a neighbour's property.
  • A converted house where rooms cross the boundary line above ground.
  • A cellar or basement reaching under the adjoining property.
  • Older terraces where upper floors overhang neighbouring buildings.

Why it matters to buyers and lenders

ConcernWhy it's an issue
Right of supportYour property relies on the structure below, which you may not own
Access for repairsYou may need to enter a neighbour's property to fix your part
Maintenance dutiesCovenants may be unclear about who repairs the shared structure
EnforceabilityPositive covenants can be hard to enforce against future owners
MortgageabilitySome lenders limit or decline lending on large flying freeholds

Most concerns come down to rights and responsibilities being undocumented or unenforceable.

Indemnity insurance often solves it

For small flying freeholds, a one-off indemnity insurance policy is commonly used to satisfy lenders. It protects against losses if rights of support or access prove inadequate, and is usually inexpensive.

How to buy a flying freehold safely

  1. 1. Tell your solicitor early

    Ask them to check the title for rights of support, access and repair covenants.

  2. 2. Check your lender's stance

    Confirm your mortgage lender accepts flying freeholds and on what terms.

  3. 3. Get a proper survey

    Have a surveyor assess the structure and the overhanging or underlying part.

  4. 4. Arrange indemnity insurance

    For small flying freeholds, a policy often satisfies the lender's requirements.

  5. 5. Consider a deed of covenant

    Where rights are missing, your solicitor may seek to put proper agreements in place.

Common questions

What is a flying freehold?

It's where part of a freehold property sits above or below land or a building you don't own, such as a room over a shared passageway. The key issues are rights of support, access and who maintains the shared structure.

Can you get a mortgage on a flying freehold?

Often yes, especially for small flying freeholds, sometimes with indemnity insurance. Large flying freeholds can limit your choice of lender, so check your lender's stance before committing to buy.

Is a flying freehold a problem?

It can be if rights of support, access and repair aren't clearly documented. Many are manageable with the right legal checks and indemnity insurance, but a large flying freehold needs specialist advice.

What is indemnity insurance for a flying freehold?

It's a one-off policy that protects against losses arising from inadequate rights of support or access. Lenders often accept it for small flying freeholds, and it's usually inexpensive.

Does a flying freehold affect resale?

A small flying freehold usually has little impact, but a large one can narrow the pool of buyers and lenders. Good legal documentation and insurance help reassure future buyers.

Should I still get a survey?

Yes. A surveyor should assess the structure, including the overhanging or underlying part, so you understand the condition and any shared-support risks before you buy.

What's the difference between flying and creeping freehold?

A flying freehold is part of your property above someone else's land or building; a creeping freehold is part of your property below someone else's. Both raise the same questions about rights and repairs.

Can missing rights be fixed?

Sometimes. A solicitor may negotiate a deed of covenant or easement with neighbours to establish proper rights of support, access and repair. Where that's not possible, indemnity insurance is the common fallback.
